Application filed May 9, 1908. Serial No. 431,891.

To all whom it may concern:

Be it known that I, JosEPH CHLEBoRAD, a citizen of the United States, and a resident of Omaha,in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Windows, of which the following is a specification.

My invention is. an improvement in windows and consists in certain novel constructions and combinations of parts hereinafter described and claimed. I

Referring to the drawings forming a part hereof, Figure 1 is a vertical section through a window constructed in accordance with my improvement. Fig. 2 is a front view of a sash. Fig.3 is a transverse section of a part of the easement, and Fig. 4 is a section of a portion of the casement on the line 44 of Fig. 3. Fig. 5 is a vertical section through a modified form. Fig. 6 is a similar view of another modification. Fig. 7- is a similar view of another modification. Fig. 8 is a view of the rear sash shown in Figs. 5 and 6. Fig. 9 is a similar view of the front sash, and Fig. 10 is a detail of the s ring connecting the two sections of the sash s own in Fig. 8.

The present embodiment of my invention comprises a circular casement 1 provided on its upper face with annular grooves 2, separated from each other by a parting strip 3, the frame being rovided on its front face with an annular ffange 4. 'The outer wall of the outer groove is provided with a rubber cushion 5, against which the frame of the upper sash to be presently described rests, and the inner wall of the rear groove is provided with a similar cushion against which the frame of the lower sash rests.- The rear cushion 5 is connected with an annular rim 6, which rim forms the outer wall of the groove, and is retained in place by an annular 7, the ring 7 being secured to the casement y screws 8. Each of the sashes comprises an annular frame 9, provided with a diametrical center rail 10, the upper face of the rail and that portion of the sash above the rail in the u per sash, and the lower face of the rail and that portion of the sash below the rail in the lower sash being grooved to receive the glass 11, as shown in Fig. 1, and the width of the frame is greater above the rail than below, to form a proper setting forthe glass. The sashes are rotatable in the casement, the bottom of the annular grooves 2 being provided at suitable intervals with friction rollers 12, journaled in the easement,-

tive ends of the ring.

and arranged with their peri heral surface projecting slightly above the ottom of the grooves. Each of the sashes is provided with a lock comprising a pin 13 slidably mounted in theframe, and adapted to engage openings 14 in the window frame, the

p1n being provided with a handle 15 for convenience in manipulating the same and being retained in locked position by a spring 16.

17 is provided which is ad'aptedto receive a pin 18, for locking the center rails of the sash together, and the bottom of the grooves at the lower art of the frame are in communication witfi of the framewhereby to provide drainage for the grooves. a-

It will be evident from the descri tion, that by releasing the locking pin 14, eit er of the sashes may be rotated in its groove, whereby to open the top or the bottom of the window, or to reverse the position of the sashes. v

In assembling the window the casement put in place, then the parting strip is inserted vAt the center of the cross bars 10, a' bearing a channel 19, leading to the front a; being in position, the front or upper sash is j and the lower sash is .put in place. The inside rim is then placed in position, and the stop 7 is secured in placeby screws 8.

It will be understood that ordinarily both sashes are precisely alike, and that the casement and the sash are made of any suitable material either wood or metal.

In the form shown in Fig. 5, the parting strip is dispensed with, and the front sash comprises a hemispherical frame 20, provided with a diametrica center rail 21, in which the glass 22 is arranged, and the said sash is fixed in the frame, the upper half of the inner face ofthe casement. being cut-away as at 23, for

receiving the sash. This cut-away portion extends rearwardly the entire thickness of the sash andbecomes annular to form a groove 24, in which is received a rin 25 having on its inner face an annular ri 26, the

said ring and the front sash being secured in place by string 27 secured to the easement by screws 28. The rear sash consists of a split ring 29, provided on its peripheral face with a groove 30, in which is received the rib 26, and

the ends of the rings are normally spaced apart from each other as at 31, the said ends being connected by a spring 32,-whose ends extend into casings 33 secured to the respec- It will be evident from the description that by pressing the casings 33 toward each other against the resistance of the spring, the ring will be contracted whereby to easily rotate in the casement, to open or close the window.

In the construction just described, the up er sash may be provided with the center rai 21 as shown in'F ig. 6, or the center rail may be dispensed with as shown in Fig. 5, and if desired the rear sash may be provided with a center rail 34, as shown'in Fig. 6, or said rail may be dispensed with as shown in Fig. 5. A pin 35 may be used to lock the .center'rails together as shown in Fig. 6, or the said pin may be omitted as shown in i- Fig.7.

In Figs. 5 and 6, the outer groove being omitted, at the bottom of the easement, the passage 19 shown in Figs. 1 and 7 is also omitted.

In Fig. 7, each of the sashes is hemis herical and the upper sash 36, is rigid in t e casement, the peripheral surface thereof having an annular recess 37 at its rear pore tion, which recess registers with an annular groove 38 in the lower part of the casement;

The inner or lower sash 39, is provided on the edge of its circular portion with a tongue 40 moving in the groove 38 and the recess 37 and the sashes are secured in place by a ring 41 secured to the casement by screws 42.
